Energy (IEC61850 Data Object:- DmdWh) Scaling from kWH to MWH in CET Tool
Is it possible to scale the Energy DmdWh (DO) in CET Tool itself. In my project, I would like to scale the energy from kWH to MWH & display in 800xA Trend & Faceplate. So, please advise how to do this in CET.
Hi Mahesh, Scaling definition is a solution for this. Like Indication Events, we need to follow the same procedure. First we need to define the scaling and the same need to be mapped in the respective analog signal's Logical Node address.
Hi. I have not tried anywhere where we have done the scaling through CET. however, from the MFM itself you can do the scaling i.e. make KWh divide by 1000 to make it a MWh value. Scaling from the MFM is easy.
Also Generally we dont make trend for KWh as it is always an incremental value
Hi Mahesh, Scaling definition option is available for all analog Logical Nodes like Voltage, Current etc., except Energy-DmdWh. To solve this, you can introduce formulas in graphics builder for Graphics and in excels for Energy Reports.
